NEW YORK, N. Y., ASSIGNOR TO LEONARD O. L. SMITH, LONG ISLAND CITY, NEW YORK HEAT, GOLD, AND SOUND INSULATING MATERIAL Application filed November 26, 1927. Serial No. 235,864.

This invention relates to heat, cold and sound cellular insulating material, formed into pads, boards, slabs and sheets of various forms and thicknesses, which also function as cushioning agents for receptacles and the like.

The ob]ect of the invention is the production of insulating material, which by reason permeated with cold air to chill all portions thereof. The fourth object of the invention is the production of an insulating material in the interior of which a partial vacuum is easily produced, to obtain the highest efficiency for the material as a heat, cold and sound insulator. The fifth object of the invention is the production of an insulating material specially applicable in the construction of refrigerators, buildings, containers, and the like.

In the accompanying drawings, Fig. 1 represents a perspective view of an exemplification of a pair of sheets of the material having incorporated therein interconnecting cells; Fig. 2 represents the-pieces of material indicated in Fig. 1, separated from each other showing additional structure; Fig. 2 indicates an enlarged section of Fig. 2 on the line 2*, 2; Fig. 2 shows an enlarged section of Fig. 2 on the line 2*, 2"; Fig. 3 represents a perspective view of a box, or container constructed of the improved insulating material; Fig. 4 shows a perspective view of a cover for the box; Fig. 5 shows a perspective view of a cylindrical container or box constructed of the improved insulating material; Fig. 6

Referring to Figs. 1 and 2 the insulating material is, in this instance, indicated to consist of a block comprising the sheets 20 and 21. Each sheet in this instance consists of interconnecting cellular material, such as newspaper pulp, wood pulp, eel grass, cornstalk pulp, wood, gypsum, clays, vegetable fibers, cork, hair and the like. In fact various fibrous or porous materials may be used. Each of the sheets is coated with a practicall air and water proof material made of, pre erably, cotton seed oil pitch. If the blocks are to be used in the construction of a container, for the protection of a cold product,.the outer faces of the blocks comprising the container has mixed with its coating of pitch white clay and the like, and the inner faces of the blocks comprising the container has mixed with its coating of pitch, aluminum powder. The special coating on the outside of the blocks prevents absorbtion of heat from the outside to the inside of the container, and the special coating on the inside faces of the blocks prevents radiation to the inside of container, providing a barrier against the passage of any heat and moisture which may have entered the sheets of the material. If a.

the container is used for the preservation of warm material the coatings just described above are reversed. Either the White clay or aluminum may be incorporated with the coating on either side of the sheet. Spar varnish, asphalt and various other water proofing materials may be used instead of the cotton seed oil pitch above referred to, and it is understood that the pitch coatings can be used without the addition of aluminum andwhite clay.

the coating of the pitch to bind them together.

Referring particularly to Fig. 2, the sheets of material are again indicated at 20 and 21. The sheet 21 has formed on its inner face a serpentine channel or conduit indicated at 23 with a longitudinal member 24. The p1tch covering is applied to all the faces of said block 21, but does not enter the serpentlne channel or its longitudinal member 24. The cross sections of the serpentine channel and its longitudinal member 24 are practically semi-circular in cross section. An Inlet valve 26 is connected to the serpentine channel at its inlet end and a similar outlet valve indirated therein a' plurality of the serpentine I formed therein and the said channels are incated at 28 is connected to the outlet end of longitudinal member 24.

When the sheet 21 is thus prepared and the sheet 20 has also been coated with the pitch coating, the adjoining faces of the sheets are connected with someof the coat-" Tieferring to Fig. 3, a box or container is shown, comprising the vertical walls 30, 31, 32 and 33'and bottom wall 34. Each of the vertical walls and bottom wall has incorpochannels or conduits indicated at 35.

The serpentine channels constitute one continuousconduit, as indicated for example in the walls 30 and 31 and are connected as indicated at 36. The channels in the bottom are also continuous and in a-similar manner are connected to the channels in the vertical walls. The inlet valve for the serpentine channel is shown at 40 and the outlet valve is indicated at 42. These valves are similar to the valve indicated at 26. The cover at 44 for the container indicated in Fig. 3 is shown in Fig. 4 and has incorporated therein the serpentine channel or condult 45 with the longitudinal member 46. Theinlet valve for the channel 45 is indicated at 47 and the outlet valve at 48, which are both similar to 26.

he inlet valves and the outlet valves 40 and 42 may be omitted, and the ends of the onduit n the container may have connecting members to the serpentine conduit 45, and by means of this construction the valves 40 and 42 may be omitted and the valves 47 and 48 function forboth the container and its cover. Referring to Figs. 5 and 6, a cylindrical container is indicated, having a vertical wall comprising the sections 50 and. a bottom 54 or channel is indicated at 55, having the inlet valve 56 and the outlet valve 57, similar to 26. The cylindrical wallmay be made in one unit Without the sections 50 referred to. The

cover for the cylindrical container is indicated at 60 with a serpentine conduit 61 having the inlet valve 62 and the outlet valve 63,

similar to 26.

Referring to Figs. 7 and 8, a plurality of sheets of the insulating material are connected to each other to constitute a block 65. The sheets of the insulating material are indicated at 70, 71, 72, 73 and 74. A serpentine channel or conduit 75 as already described is provided for the sheet 70, a serpentine connected thereto. The serpentine conduit of the insulating material are indicated. at 90 and 91. In the sheet 91, is incorporated the serpentine conduit 92 having the inlet valve 93 and the outlet valve 94. This modification is used when a plurality of the blocks are'lo- I cated horizontally in line with their vertical sides abutting against each other.

Referring to Fig. 11 there is shown a plurality of pads, sheets or pads of material each of which is indicated in its entirety by the numeral 98. Each pad has a'channel 99 111, similar to 26. An additional sheet of the insulating material is indicated at 115 with a serpentine conduit having the inletvalve 116 and the outlet valve 117. The serpentine channels withthe valves 110 and 111 outside surface thereof would comprise'the pose of creating a bla sheets 105 and the inside surface of the container would comprise the sheets 115. The serpentine channel with the valves 116 and 117 is used for holdin cold gas for the pur- 15ml, of cold as around the product being preserved. T e conduit having the valves 110 and 111'contain a partial vacuum and are for the gurpose of maintaining the temperature of t other conduit.

Referring to Fi 13 a sheet of the heat cold and sound ce ular insulating material similar to 20, is indicated at 120, and has connected thereto the inlet opening 121, at

15 one end, and the outlet opening 122, which without the use 0 any ser entine conduit as are directly inserted in end material and to which valves may be connected. The said valves are directl inserted in said materlal go indicated at 23 and 24 in i 2.

It is to be noted that the s eets and blocks described may constitute the walls of a container without any outside receptacle therefor, but they may also constitute the inside 26 lining of a container. The container 'ust described of insulating material may ocated within an outside container of varlous different materials. Also a container of vanous materials may be located within the conso tainer of insulating material. By' this construction there is produced a container with an outside shell, an inside shell, and a linin between them of insulating material. n Fig. 14 is indicated a sheet of the maa5 terial 125 similar to having channels 126 .on its outer face. In Fig. 15 is shown a cover 127 made of the cellular material with the channels 128 on its outer face. In Fig. 16
